God damn, what kind of solar setup is this? You said you don't need batteries for backup? How is that even possible? What happens once the sun goes down in the evening and night? Wowu
My solar farm is tied to the grid. So anything I produce in excess of what I consume, flows back into the grid. At night and on cloudy/rainy days, I draw power from the grid. With the Net Metering arrangement I have, I'm credited for every kWh I put back into the grid at the same rate they charge me, i.e. ~ $0.12 per kWh.
